WATCH-STRAP.

Specification of Letters Patent.

Patented Apr. 10, 1917.

Application iiled November 2, 1916. SerialNo. 129,217.

To all whom it may concern:

. Be it known that I, EDWARD GRUIKSHANK GRANT, a subject of the King of Great Britain, and residing at 24 Blackburn avenue, in the city of Ottawa, in the county of Carleton, Province of Ontario, and Dominion of Canada, have invented certain new and useful Improvements in VVatch-Straps, of which the following is the specification.

This invention relates to improvements in watch straps particularly adapted for use with wrist watches, and the objects of the invention are to facilitate securing a wrist watch in position without the necessity of holding the same during the operation,. to permit of the strap being readily adjusted to suit the wrist of the wearer, to prevent falling should the strap inadvertently become undone and generally to adapt the several parts to better perform the functions required of them.

With the above and other objects in view the invention consists essentially of the improved construction particularly described and set forth in the following specification and accompanying drawings forming part of the same.

In the drawings,

Figure 1 is a perspective view of the strap as seen when in a closed position.

Fig. 2 is a perspective view of the strap as seen when opened.

Like characters of reference refer to like parts in the several figures.

Referring to the drawings, A represents the improved device comprising the strap 10 provided at one end with a link 11 through which the free or other end of the strap is designed to be passed in a manner to be made clear hereafter.

Slidably mounted on the strap 10 is a guard 12 provided at opposite ends with tubular guides 13 and 14 through which the strap passes, the said guard being provided intermediate of its length with a slot 15 which permits of the guard readily yielding to conform to the contour of the wrist of the wearer.

being readily adjusted on the strap 10 and at the same time provide means for automatically interlocking therewith. This hook member, it will be understood, is of sufficient size so that it cannot slip through the link 11 and should the hook member become inadvertently disengaged from the tubular guide member 14, the strap 10 will hang on the wrist of the wearer so that the watch cannot fall. On this hook member 18 is imprinted or otherwise delineated the name, number, or other identification mark of the wearer.

When the device is in use, the strap 10 is first passed through the tubular guide member 13 and then through the staples provided on the ordinary wrist watch, whereupon the strap is passed through the tubular guide member 14 and through the link 11.

It will thus be seen that the guard 12 is located on the loop formed by passing the free end of the strap 10 through the link 11, and the said guard may be adjusted on the strap so that it will occupy the desired position on the back of the wrist of the wearer. The hook member 18 is now attached to the free end of the strap 10 by passing the same through the slots 16 and 17.

The strap 10 is pulled through the tubular guide members 13 and 14 until the link 11 is located adjacent to the member 13 which is the normal position of the said link and the loop formed by passing the strap 10 through the link 11 is placed around the wrist of the wearer and the strap 10 is bent backwardly on itself so that the hook member 18 is engaged with the tubular .guide member 14, thus securing the strap and Watch carried thereby in position.

Should it be found necessary to adjust 1 the strap to increase the wrist engaging loop, it is only necessary to pull the strap through the tubular guide members 13 and 14 until the link 1.1 assumes a position shown in Fig. 1, whereupon the hook member 18 is engaged withthe tubular guide member 14.

It will be clear that by attaching the hook member 18 in the manner above described, it will automatically interlock with the strap 10 and cannot accidentally work loose while the required effective length of strap is readily obtained by adjusting the position of the hook member 18 to suit the requirements.

The use of the guard member 12 prevents the back of the watch coming in contact with the wrist.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention within the scope of the claims, constructed without departingfrom the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limited sense.

What I claim as my invention is:

1. A device of the class described, com prising a strap, a link on one end of the strap through which the other end of the strap passes, a Watch guard having tubular guide members slidably engaging with the strap and catch means on the free end of the strap adapted to engage one of the tubular memnaaaeei prising a strap, a guard member adjustably ,prising a strap, a link on one end of the strap through which the other end of the strap is designed to pass, a catch member having a pair of parallel arranged slots on one end designed to engage with the free end of the strap and a guard member slidably mounted on the strap including means adapted to engage with the hook member.

In Witness whereof I hereunto set my hand.

EDWARD GRUIKSHANK GRANT.
